a little more on the shopping cart thing. I'm having a lot of trouble figuring out which cookies are set where, when, how, and why for zen carts sessions.

I tried to make a redirect based off sessions on a page that had nothing to do with zen cart and just couldent get it working even with my own unique named session.


Code:
<?php
session_start();
require_once('inc.functions.php');
$_SESSION['redirected'] = 1 ;

//redirect them now

header('Location: index.php');
?>
none of that worked. session wouldent set or would be over written in zen cart or i have no idea.
